Create an ultra-photorealistic luxury fashion editorial poster in a vertical 4:5 aspect ratio. Combine two photographic portraits of the SAME adult person against a deep black studio background: an oversized black-and-white close-up on the left and a smaller, full-color seated portrait in the center-right foreground. IDENTITY If a portrait reference is uploaded, use it as the authoritative identity reference for BOTH portraits. Preserve her recognizable facial structure, age, complexion, eye shape, nose, lips, and natural proportions. Both views must clearly depict the same woman, with consistent hair length and texture. Without an identity reference, depict an adult woman with softly defined facial features, full lips, and long, voluminous honey-brown hair with golden highlights. BACKGROUND PORTRAIT Place an enormous monochrome head-and-upper-chest portrait across the left two-thirds of the composition, extending beyond the top and left edges. Her face occupies the upper-left area, turned slightly toward the camera, chin subtly raised, with a calm, self-assured expression and softly parted lips. She wears narrow rectangular black sunglasses with dark lenses and a fine dark frame. Long, thick, loosely curled hair surrounds her face and falls across her shoulders, with individual strands and soft flyaways visible. Dress her in a black open-neck blouse with a delicate chain necklace and a small round pendant. Render this portrait in rich black and white, with luminous skin, detailed midtones, and deep shadows. Gradually fade its lower chest, outer hair, and right shoulder into the black background using a soft photographic mask. Keep the face distinct and beautifully detailed. FOREGROUND PORTRAIT Position the full-color version of the same woman seated on a low, round, black leather ottoman in the lower center-right. Show her entire body, including both pointed shoes, with a small margin beneath them. She wears a lustrous black satin button-front blouse with a relaxed open collar, long sleeves, and natural folds at the elbows and waist. Pair it with flowing, tailored black wide-leg trousers and glossy black pointed-toe stiletto pumps. Include a delicate pendant necklace.
